Monitoring using fibre optics

Fibre optics are widely used for communication technology such as internet networks. There are numerous other applications in the geosciences, one example being measurements of parameters like temperature and strain. There are multiple advantages. Fibre-optic cables are cheap and do not wear over time. Moreover, measurements are accurate and they are not affected by electromagnetic radiation, corrosion, moisture or water. Typically, accuracies are within 0.1°C, spatial resolution ranges between 0.002 m and 2.0 m, and measurement frequencies are up to 1 Hz.
